Hot Melt Glue

A Cdn. supplier sent me this this morning...
Do you know what makes a glue stick "Hi-Temp"?
It's not actually about the melting point!

It's got to do with the kind of glue guns you can use them in. Long story short, you'll want to use the "Hi-Temp" glue sticks for metal & plastics and the "All-Temp" glue sticks in combination with a Low Melt Glue Gun for heat sensitive materials like styrofoam and polystyrene.

The "Hi-Temp" glue sticks have a viscosity of 11,000 ~ 13,000 which makes them suitable for non-porous materials such as metals, and plastics.

However, the "All-Temp" glue sticks have a lower viscosity of 9400 which makes them suited for both porous and non-porous materials. That makes them a suitable option for "Low Melt" Glue Guns because you're typically only using those on porous materials. Both the Hi-Temp and All-Temp glue sticks have a melting point of 80ºC.
I quite like these guys...

Generally the darker yellow they are, the stronger the bond. The strongest one that I know of is Bohning's Ferr-L-Tite which traditional archers use to glue steel points on wooden arrow shafts. https://www.amazon.com/Bohning-1309-Fer ... B0009TUDRW

I have a glue gun in the shop and use it sometimes to glue parts of jigs together. It's as fast as super glue but you can take it apart after. It's also handy for making zero clearance inserts for a table saw. Just glue the OEM insert to some mdf with a few dabs of hot melt and use a pattern bit to rout the zero clearance one to size. Then pop them apart.

I designed and built a machine to automatically machine and assemble the nozzle for the first hot glue gun, for USM (United Shoe Machinery). Although they still carried that name, they were coming up with all kinds of useful products. Hot Glue Guns and Pop Rivets and the tools for installing them initially came from USM. This first machine was installed at Eastern Casting, in Newburg, NY because they were casting the nozzles, then machining the casting, and drilling the nozzle tip and heating element socket, then inserting the heating element. The machine was fully automatic but the castings were inserted into a holding chuck as they came by one at a time by the operator. Everything from then on was fully automatic and they went into a big box automatically via an air jet puff at completion. That was back about 1962. Eastern Casting was the hottest place that I ever had to work.
